Chromium—Makes Stainless Steel Stainless Chromium, a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point, is a silvery white, hard, and bright metal plating on steel and other material. Commonly known as chrome, it is one of the most important and
At elevated temperatures all metals react with hot gases. The most common high temperature gaseous mixture is air, and oxygen is the most reactive component of air. Carbon steel is limited to ~900 °F (480 °C) in air. Chromium in stainless steel reacts with oxygen to form a chromium oxide scale which reduces oxygen diffusion into the material.

Dec 16, 2018· Often used in chromium-nickel austenitic steels, molybdenum protects against pitting corrosion caused by chlorides and sulfur chemicals. Nickel (2-20%): Another alloying element critical to stainless steels, nickel is added at over 8% content to high chromium stainless steel.
D2 Tool Steel. D2 Tool Steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials.
JIS G4805 is standard which specifies the high carbon chromium bearing steels used for roller bearings. It's similar to ISO 683, DIN 17230, ASTM A295, GB/T 18254 and BS 970 etc. In JIS G4805 specifications, the bearing steels shall be classified into 5 steel grades: SUJ1, SUJ2, SUJ3, SUJ4, SUJ5.
This steel has good edge holding properties and high corossion resistance, but is more difficult to resharpen than lower chromium steels. 60-61: AUS 6A: A medium to high carbon stainless steel, this steel holds a good edge and is particularly well suited for heavy, long blades that are subjected to a lot of stress while chopping and hacking.
